Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of surge protectors, and particularly relates to a combined surge protector. Background Art
[0002] A surge protector, also called a lightning arrester, is an electronic device that provides safety protection for various electronic devices, instruments, and communication lines. When a sharp peak current or voltage suddenly occurs in an electrical circuit or communication line due to external interference, the surge protector can conduct and shunt in an extremely short time, thereby avoiding damage to other devices in the circuit caused by surges. For example, the surge protectors installed on some electromechanical devices are generally installed externally. After a long time, fine dust will deposit on the wiring terminals of the protector, etc., which will affect the normal use of the surge protector. However, during the use of the current combined surge protector, there is a lack of a structure for dust-proof protection on its exterior, so that the surge protector cannot be better protected. Moreover, the wires of the surge protector are generally fixed to the wiring terminals by screws, and the screws used for fixing are prone to slipping threads, which will affect the wiring work of the surge protector. Therefore, we propose a combined surge protector to solve the above problems. Content of the Utility Model

Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.
[0024] Embodiment
[0025] Such as Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5As shown in the figure, a combined surge protector proposed by an embodiment of the present utility model includes a housing 1. Mounting plates 14 are fixed on both the upper and lower surfaces of the housing 1. Two mounting holes are provided on the side walls of the mounting plates 14, which makes it more convenient to operate when installing and fixing the housing 1. A cover plate 2 is inserted into the housing 1. An L-shaped push plate 17 is fixed on the surface of the cover plate 2, which facilitates separating the cover plate 2 from the housing 1. A protector body 3 is clamped inside the housing 1. Wiring structures 4 are provided at the wiring ends of the protector body 3. Mounting frames 5 are fixed at the air inlets provided on both side walls of the housing 1. Filter nets 6 are tightly inserted into the slots provided in the mounting frames 5. An exhaust fan 7 is fixed inside the through hole provided at the bottom of the housing 1. A dust-proof cover 8 fixed to the bottom of the housing 1 is provided below the exhaust fan 7. A lower inlet pipe 9 is connected and fixed to the bottom of the housing 1. Four upper inlet pipes 10 are connected and fixed to the top of the cover plate 2. Sealing rings 11 are fixed inside the lower inlet pipe 9 and the upper inlet pipes 10. When using this combined surge protector, the housing 1 can be fixed at a suitable position. When wiring the protector body 3, one end of the lower connecting wire can be passed through the lower inlet pipe 9 and limited and fixed on the lower wiring end of the protector body 3. Then, the protector body 3 can be clamped inside the housing 1. When wiring the upper wiring end, one end of the connecting wire can be passed through the corresponding upper inlet pipe 10. Then, one end of the wire can be fixed on the wiring structure 4 of the corresponding wiring end. At this time, the wiring work of the protector body 3 can be completed. The sealing rings 11 provided inside the lower inlet pipe 9 and the upper inlet pipes 10 can play a role in dust prevention at the wiring ports. After wiring, the cover plate 2 can be clamped on the surface of the housing 1, which can play a role in dust-proof protection for the protector body 3. And during the use of the protector body 3, starting the exhaust fan 7 can suck the external air into the housing 1 and discharge it, and at this time, rapid heat dissipation of the protector body 3 inside the housing 1 can be achieved.
[0026] As Figure 2 and Figure 6As shown, in some embodiments, the wiring structure 4 includes a support plate 401 fixed to the wiring terminal of the protector body 3. A guide block 402 is fixed to the top of the support plate 401. Two cross clamps 403 are slidably connected inside a T-shaped groove formed in one side wall of the guide block 402. A U-shaped plate 404 is fixed to the top of the support plate 401. An L-shaped moving rod 405 slidably penetrates through the top of the U-shaped plate 404. A pressing block 406 adapted to the cross clamps 403 is fixed to the bottom end of the L-shaped moving rod 405. A spring 407 is fixed to the top of the pressing block 406. The top end of the spring 407 is fixedly connected to the inner wall of the top of the U-shaped plate 404. When connecting the conducting wire, the L-shaped moving rod 405 can be operated to drive the pressing block 406 to move upward. When the pressing block 406 moves upward, the spring 407 at this time will be in a compressed state, and the restriction on the two cross clamps 403 can be released after the pressing block 406 moves upward. At this time, one end of the wire bent into an L shape can be first passed through between the two cross clamps 403 and placed below the pressing block 406. Finally, the L-shaped moving rod 405 is released. At this time, under the restoring force of the compressed spring 407, the pressing block 406 can press the wire tightly, and when the pressing block 406 moves downward and presses tightly, it can drive the two cross clamps 403 to move towards the middle position at the same time. At this time, the two cross clamps 403 can clamp the wire, so as to realize the limit fixation of the wire with one end bent into an L shape. Anti-slip ridges are respectively fixed to the bottoms of the cross clamps 403 and the pressing block 406, so that one end of the wire will be more stable after being fixed.
[0027] As Figure 2 , Figure 3 and Figure 4 As shown, in some embodiments, a cathode magnetic strip 12 is fixed inside a counterbore formed in the top of the housing 1. An anode magnetic strip 13 is fixed to the inner wall of the top of the cover plate 2. The anode magnetic strip 13 attracts the cathode magnetic strip 12. With the cooperation of the cathode magnetic strip 12 and the anode magnetic strip 13, the cover plate 2 will be more stable after being clamped and limited inside the housing 1.
[0028] As Figure 1 and Figure 4 As shown, in some embodiments, a frame 15 is fixed inside a through hole formed in the front of the cover plate 2. A transparent plate 16 is fixed inside the frame 15. Without opening the cover plate 2, it is convenient for the staff to check the working state of the protector body 3.
[0029] Finally, it should be noted that the above are only the preferred embodiments of the present utility model and are not used to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions recorded in the foregoing embodiments or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
